凯迪拉克车系采用了能测出前窗玻璃上的水量并相应地自动调节刮水器的雨敏智能系统。开始下雨或下雪时,雨敏系统启动刮水器,根据水量大小自动调节刮水动作的间隔时间。下大雨时,利水器的速度先慢后快;降水停止时,利水器也不再动。雨敏系统是1996年款凯迪拉克帝威尔(DeVille)、康克(Concours)、赛威尔(Seville)和爱都(Eldorado)的标准设备。 雨敏系统的核心是一个小模块,装在前窗玻璃内、后视镜的后面。一排8个微小的发光二极管发出红外线,斜着穿过玻璃。如果前窗玻璃是干的,红外线从玻璃外表面反射回来,被模块另一面8个探测器接收。 如果玻璃上有水,玻璃表面不会精确地反射光束,模块就探测到外面有雨或雪。 探测到前窗玻璃上有水是一回事,精确地测出水量以调节利水器是另一回事。雨敏模块分别用两个输入做到这一点。它测量刮一 Cadillac cars used to measure the amount of water on the windshield and automatically adjust the wiper rain smart system accordingly. When it starts to rain or snow, the rain-sensitive system activates the wiper and automatically adjusts the wiper interval based on the amount of water. When it rains, the speed of the digester slows down first and then when the precipitation stops, the digester no longer moves. The rain-sensitive system is standard equipment for the 1996 Cadillac DeVille, Concours, Seville and Eldorado. At the heart of the rain-sensitive system is a small module housed in the front glass and behind the rear-view mirror. A row of eight tiny light-emitting diodes emit infrared light, diagonally across the glass. If the front glass is dry, the infrared light is reflected back from the outer glass surface and received by the 8 detectors on the other side of the module. If there is water on the glass, the glass surface does not accurately reflect the light beam and the module detects rain or snow on the outside. It is one thing to detect that there is water on the windshield, and it is quite another to measure the amount of water accurately to regulate the water. Rain-sensitive modules do this with two inputs respectively. It measures a scratch
